[ BUILD # : ef67b41cc450 ]
[ JDK VERSION : 1.6.* ]

Follow this steps:
1. Create a new main class like this:

public class NewMain {
   public static void main(String[] args) {
      final String str = "abc";
      str.toString();
   }
}

2. Select the line 3, 'final String str = "abc";', and hit code template
'Surround with if (exp)...'

the generated code will be:

public class NewMain {
   public static void main(String[] args) {
      String str = null;
      if (exp) {
         final str  = "abc";
      } else {
      }
      str.toString();
   }
}

and the expected is remove 'final' keyword.
